The US' socialists didn't fade quietly they were killed or imprisoned. The unions didn't turn into pathetic electoral/crime machines without some serious cracking down on their socialist leanings. Without a convergent succession of red scares and with more radical founding for the freedomites, I had some hope their pro labour wing would have more luck down the line, since there was quite a bit of overlap with radical labour politics. Like, Lincoln literally corresponded with Marx and talked about the primacy of labour over capital, and he's too moderate for them.
Yes, but 1) the very radical people like Benjamin Wade were a minority in the party and 2) by the 1870s and 1880s, the OTL Republican Party had changed, as does the Freedom Party ITTL, to become more business-friendly. It might be a bit convergent to have the Freedom Party end up so similar to the Republican Party of the 1880s, but I think there are some things that have enough probability of happening that it would be unrealistic to specifically avoid them. The more divergent part TTL is that the Freedom Party
stays the party of the 'Eastern Establishment'.
Also, there's not going to be any Red Scares. Communism, while it will still exist, will not be such an influential ideology as it was OTL.
I'm also seriously tired of "what if the center left was socially conservative, wouldn't that be a lark", which completely ignores the material reasons why the economically right wing party always end up drifting towards being the social conservative one over time (they need non economic reasons for non wealthy people to vote for them).
At least we can vote for Debs' corpse and act as spoiler I guess.
The National Party isn't socially conservative like the Republican Party is today. It's socially conservative like William Jennings Bryan was. Rather than rail about abortion, it wants morality laws regulating public drunkenness, Sunday business, gambling, and the like. It's a populist party that appeals to farmers who need aid, blue-collar workers, Evangelicals who support outreach and welfare, and the like. The unions begin to back the Nationals during the Powell administration, due to its pro-labor policies.
The Freedom Party is not exactly economically right wing. They are in favor of things like welfare and social spending. They tend to oppose austerity measures. Where they differ is, of course, over social issues, business regulations, and whether Unions need oversight and investigations. The way the Freedom Party attracts swing voters in industrial states like Pennsylvania is by convincing them that reducing business regulation will expand work benefits and job opportunities by giving businesses more income to spend on expansion and retention (not that businesses work that way, but it's easy for a party to convince people of that, especially given how hard it is to disprove that lower regulations improve jobs growth). They also win over some workers by promising to seek understanding between business and labor, by overseeing negotiations and by negotiating with business leaders. In like states like Fremont and Sacramento, they use anti corruption rhetoric to bring over swing voters in where unions don't hold much sway. Also, it's not hard for a economically center-right, socially liberal candidate to win. Nixon came very close in 1960. Dewey could have won if he was more aggressive in campaigning. William McKinley won twice. Garfield won. Harding won in a landslide (though the Freedom Party is more liberal than Harding).
